isn't this odd? leaves me confused!

Super confused, originally my 2nd ovulation week in December was at Dec. 27 start. Well my very odd period that was 2.5 days ended, I took a ovulation test day of last period out of curiosity. ZERO hormone found aka low chances. NEXT day, took another said I was at Peak fertility aka releasing an egg day. what!?! do u go from no hormone to BAM highest. no high fertility days just straight PEAK. updated my glow, and it then moved my ovulation week up a bit at you can see the start day, tomorrow's already my last day when originally it wasnt even to start until the 27th, Wednesday. super confused? my bodys suddenly ovulating early this month? anyone else? no never heard of it. tell me ur thoughts!
